CAT bonds are of significant importance in the field of alternative risk transfer. Since the market of CAT bonds is not complete, the application of an appropriate pricing model is of high relevance. We apply different premium calculation models in order to compare them with regard to their...

(CAT-)astrophe Bonds are of significant importance in the field of alternative risk transfer.Since the market of CAT Bonds is not as liquid as e.g. the stock market, the use of pricing models is ofhigh relevance. One important parameter in all pricing models is the probability of catastrophe....

We extend the continuous Cumulative Prospect Theory (CPT) by considering piecewise con-tinuous distributions with a finite number of jump discontinuities. Such distributions are rele-vant in practice, for example, within the framework of financial engineering since cash flow distributions of...

The measurement of concentration risk in credit portfolios is necessary for the determination of regulatory capital under Pillar 2 of Basel II as well as for managing portfolios and allocating economic capital. Existing multi-factor models that deal with concentration risk are often inconsistent...

According to the new capital adequacy framework (Basel II) finally adopted by the Basel Committee in June 2004 the eligibility of collaterals, especially financial collaterals, is extended in comparison to the existing rules. However, financial assets are valued conservatively in the credit...

A non-stationary regression model for financial returns is examined theoretically in this paper.Volatility dynamics are modelled both exogenously and deterministic, captured by a nonparametriccurve estimation on equidistant centered returns. We prove consistency and asymptotic normalityof a...

In this paper we first investigate the validity of a general Value at Risk approach, which iswidely used for risk management in banking and insurance companies. We discuss and widely rejectthe conventional assumptions, e.g. independent identically distributed normal returns, and as...
